How to renew eth0 settings without doing a reset

How to renew eth0 settings without doing a reset

[Haris Papadopoulos]

Hi,

I am trying to configure a static ip address for my barebox.

I edit the file /env/network/eth0 and then I do saveenv.

Then I do ifup eth0. There is no ifdown command in barebox.

I noticed that the only way to make the new ip address effective is to
reset the board. However, I will be doing this process with a script
or maybe remotely.

Therefore, I would like to make the new address effective without a
reset. How is that possible?

Thanks
Haris

Have you tried the ifup command's -f option to force it to reconfigure 
the interface?

I'm not sure when that option was added to barebox.

eth0.ipaddress=1.2.3.4

should work
